Auto Original 47 is an autoflowering cannabis cultivar developed by JustFeminized.com, a breeder known for feminized and autoflowering lines. The strain’s name signals a classic, balanced hybrid ethos while emphasizing the autoflower trait contributed by Cannabis ruderalis. In context, JustFeminized.com targeted a dependable home-grower profile: compact plants, predictable flowering, and a broad hybrid effect.
Because autoflower varieties rely on day-neutral flowering, breeders typically combine a photoperiod hybrid with ruderalis and backcross across several generations. That process is essential to fix the rapid life cycle while preserving potency and yield. In most projects, breeders complete multiple filial generations to stabilize morphology and chemotype, resulting in the consistent seed lots that hobbyists expect.
Publicly available specifics on the exact photoperiod parents for Auto Original 47 are limited, a common practice among commercial seedmakers to protect proprietary lines. What is clear from grower reports is a hybrid phenotype with both indica and sativa expressions and a reliable finish without light-cycle manipulation. In practical terms, this means most gardens see harvest in roughly 70–85 days from sprout, depending on environment and feeding.
The early popularity of autos in Europe, where balcony and micro-grows are common, likely shaped the development brief for Auto Original 47. Space efficiency, discreet aroma control, and abbreviated turnarounds are frequent priorities for that audience. By marrying those needs with modern potency, the breeder positioned this strain for both first-time growers and experienced cultivators seeking quick, repeatable cycles.
Genetic Lineage and Taxonomy
Auto Original 47’s heritage is a ruderalis/indica/sativa blend, which translates into a balanced hybrid with day-neutral flowering. The ruderalis component confers the autoflower trait, triggered by plant age rather than photoperiod. The indica contribution often drives compact stature and thicker lateral branching, while sativa influence can add stretch, floral complexity, and a brighter head effect.
In practical taxonomy, expect a hybrid that leans slightly indica in structure but behaves like a modern 50/50 in effects. Growers often note internodal spacing that is tighter than typical sativas, yet less dense than pure indicas, making airflow management straightforward. That architecture pairs well with low-stress training without requiring aggressive topping.
While the exact photoperiod parents remain undisclosed, the “47” naming convention historically nods to high-impact hybrids with a notable balance of cerebral clarity and body ease. It is best to avoid assuming a specific marquee lineage without breeder confirmation. Instead, growers can make practical decisions based on the visible hybrid morphology and the reliable ruderalis-driven life cycle.
Visual Appearance and Plant Morphology
Mature plants tend to reach 60–100 cm indoors, which suits tents and closets, while outdoor specimens in full sun can stand 80–120 cm. The canopy is typically conical with a dominant central cola and several productive side branches. Internodes are moderate, allowing light penetration with minimal defoliation.
Foliage shows a hybrid leaf shape with medium-width blades and a healthy green hue when nutrients are balanced. Late in flower, phenotypes may express subtle anthocyanins at the sugar-leaf tips in cooler nights around 16–18°C, though not all plants will color. Trichome density is high on bracts and sugar leaves, forming a cloudy blanket that becomes the main indicator for harvest readiness.
Buds are compact to medium dense, with a calyx-to-leaf ratio that favors relatively easy manicuring. Pistils start pale and shift from cream to burnt orange as they mature, typically with 70–90% oxidation by harvest for most growers. Resin coverage is often notable for an autoflower, a testament to modern ruderalis breeding progress.
When dried and cured well, the flowers hold their shape and offer a firm hand feel, neither airy nor rock-hard. Well-grown batches can yield 14–18% moisture loss post-dry, stabilizing near 10–12% moisture for curing in glass. This structural resilience helps preserve bag appeal over months when stored at 58–62% relative humidity.
Aroma: Volatile Profile and Nose
Auto Original 47 presents a layered aroma that many growers describe as sweet-earthy with flashes of spice and citrus. The top notes often feature a bright lemon-lime snap suggestive of limonene, while the base is grounded in loam, incense, and a slight peppery tickle aligned with β-caryophyllene. Some phenotypes lean more toward floral, with hints of lilac and green tea.
In a jar or after a light squeeze, mid-notes develop into a mild fruit rind character—think grapefruit pith and green mango—alongside a fresh pine lift from α- or β-pinene. During grind, expect sharper, savory components to stand out, including a faint diesel wisp that dissipates quickly when aired. These contrasts give the strain a complex nose that changes from bag to grinder to bowl.
Across cured samples, terpene intensity can vary from subtle to pronounced depending on drying and curing discipline. Samples dried too quickly above 23–24°C often lose their brightest citrus top notes within the first week. When dried at 18–20°C and 50–60% relative humidity, the bouquet typically stays vivid for 60–90 days with minimal fade.
Flavor and Combustion/Vapor Quality
The flavor mirrors the aroma with sweet-citrus entry, herbal mid-tones, and a peppery finish. On a clean glass piece, the first draw suggests lemon zest and sweet hay, transitioning to mild spice and cedar on the exhale. A faint resinous pine lingers on the palate, contributing to a crisp aftertaste.
When vaporized at 175–185°C, citrus and floral components are most pronounced, with a softer finish and minimal throat harshness. At higher vape temps around 195–205°C, the peppery caryophyllene and herbal myrcene become more obvious, and the vapor feels fuller. In joints or blunts, the flavor leans earthier and bready as combustion favors Maillard notes and caramelization.
Well-cured flowers show white-to-light gray ash and a smooth burn, indicating proper mineral balance and post-harvest handling. Overfeeding late in flower or an insufficient flush can introduce bitterness and dark ash, overshadowing the delicate citrus edge. Experienced users often note that the best flavor appears after 14–21 days of curing, with a peak around week four.
Cannabinoid Profile and Potency Expectations
While exact lab averages for Auto Original 47 are not universally published, autoflowering hybrids with similar breeding generally test in the THC 16–22% range. Phenotype, environment, and harvest timing can push outliers lower to 14% or higher to 24% THC in exceptional runs. CBD is typically low, often 0.1–0.8%, while total cannabinoids frequently fall between 18–26%.
Minor cannabinoids like CBG often appear around 0.4–1.2%, which can contribute to perceived smoothness and mood lift. Trace CBC and THCV may be detectable in the 0.05–0.3% band, though these fluctuate more widely with environmental stress and maturity. Growers who harvest with more cloudy than amber trichomes often report a brighter head effect, whereas amber-heavy harvests lean sedative.
For dosing, inhalation typically delivers noticeable effects within 5–10 minutes, peaking at 30–45 minutes and tapering over 2–3 hours. Edibles derived from this chemotype often require 45–90 minutes to onset and last 4–6 hours, with a stronger body component. New consumers should start low, around 2.5–5 mg THC orally or 1–2 small inhalation pulls, then titrate slowly.
Terpene Profile and Chemistry
Growers and third-party tests from similar hybrid autos often show myrcene, β-caryophyllene, limonene, and pinene as dominant terpenes. Total terpene content commonly falls between 1.2–2.5% by dry weight when grown under optimized conditions. Myrcene in the 0.4–0.9% range can underpin the earthy-sweet baseline and modest physical relaxation.
β-Caryophyllene, often 0.3–0.7%, contributes peppery spice and is notable for binding to CB2 receptors in vitro, a unique feature among terpenes. Limonene, commonly 0.2–0.6%, is associated with bright citrus aroma and a mood-elevating perception in user reports. α- and β-Pinene in the 0.1–0.4% range add conifer notes and may influence perceived clarity.
Secondary terpenes can include linalool (floral, 0.05–0.2%), humulene (woody, 0.05–0.2%), and ocimene (sweet-herbal, trace to 0.15%). The exact distribution varies by phenotype and post-harvest process, with rapid, warm drying eroding ocimene and linalool faster than more robust hydrocarbons. A slow cure often integrates the citrus, floral, and spice elements into a cohesive profile.
Experiential Effects and User Reports
Auto Original 47 tends to deliver a balanced hybrid experience: a clear, upbeat head effect coupled with gradual body ease. Many users report initial mental clarity and mood elevation within the first 15 minutes, followed by soft muscular relaxation. The line generally avoids overwhelming couchlock at moderate doses, although late-night use can become sedative, especially with amber-heavy harvests.
Cognitive effects often include mild euphoria, enhanced appreciation for music or conversation, and a gentle focus. At higher doses, a broader body heaviness and time dilation are possible, and some individuals may experience transient anxiety if sensitive to THC above 18–20%. Hydration and pacing doses help minimize discomfort, with most side effects dissipating as plasma THC declines.
Appetite stimulation is common about one hour post-inhalation, useful for evening meals or recovery windows. Social settings benefit from the talkative, relaxed mood, though the peppery-spice nose can be pungent indoors and may require ventilation. Many users consider it a day-to-evening strain, leaning more evening if harvested later or consumed at higher quantities.
Potential Medical Applications and Considerations
Patients and caregivers often look to balanced hybrids like Auto Original 47 for stress, low mood, and generalized tension. The limonene and pinene components are frequently reported to support a clearer, uplifted headspace, while myrcene and caryophyllene can contribute to body ease. Anecdotally, users with situational anxiety sometimes prefer small, titrated doses to avoid THC-induced jitteriness.
For pain, several meta-analyses on cannabinoid therapies suggest modest to moderate reductions in chronic pain intensity versus placebo, frequently in the 20–30% improvement range. β-Caryophyllene’s CB2 activity is of particular interest for inflammatory pathways, though human clinical data specific to this strain are not published. Users report relief for tension headaches, post-workout soreness, and low-grade neuropathic discomfort when doses are managed thoughtfully.
Sleep outcomes depend on timing and harvest maturity. Earlier harvests with fewer amber trichomes may feel too stimulating near bedtime, whereas later harvests can show more soporific effects, attributable in part to oxidation byproducts like CBN and a heavier myrcene-caryophyllene signature. As always, individuals with underlying conditions should consult a clinician and start with conservative dosing.
For appetite and nausea, THC has documented orexigenic effects that many patients find helpful, especially during convalescence or appetite dips. Edibles or tinctures derived from Auto Original 47 can provide longer-lasting support for evening meals. Patients should monitor interactions with other medications and avoid driving or operating machinery while under the influence.
Comprehensive Cultivation Guide
Auto Original 47 was bred by JustFeminized.com and expresses the ruderalis/indica/sativa heritage in a compact, reliable autoflowering package. Most gardens see seed-to-harvest timelines of 70–85 days, with vigorous phenotypes finishing on the earlier end under optimized light and nutrition. The autoflower trait eliminates the need to switch to 12/12, streamlining planning for continuous or staggered harvests.
Light schedules of 18/6 or 20/4 throughout the cycle are common, with 18/6 offering a good balance of growth and equipment wear. Indoor PPFD targets of 600–900 µmol/m²/s in mid-to-late flower are effective, translating to a daily light integral around 30–45 mol/m²/day. Maintaining light intensity uniformity within ±10% across the canopy helps keep colas consistent.
Temperature targets of 24–27°C during the day and 18–22°C at night support enzymatic activity and terpene retention. Relative humidity should start around 60–70% in early veg, then taper to 50–55% mid-flower and 45–50% late flower to reduce botrytis risk. A vapor pressure deficit of 0.8–1.3 kPa across the cycle generally aligns with healthy transpiration for autos.
In soil, aim for a pH of 6.2–6.8; in coco or hydro, maintain 5.8–6.2 to optimize nutrient availability. EC for autos is usually milder than for photoperiods: 0.8–1.2 mS/cm in early veg, 1.2–1.6 mS/cm in mid-flower, and peak around 1.6–1.8 mS/cm if the plant signals hunger. Overfeeding is the most common mistake with autos and can stunt growth during their short vegetative window.
Pot sizes of 11–19 liters (3–5 gallons) are ideal for final containers because transplant stress can cost critical days. If you must transplant, do it once from a small starter plug to the final pot by day 10–14 from sprout. Inert mediums like coco coir with 30–40% perlite deliver fast growth when irrigated daily to 10–20% runoff.
A typical feed curve favors higher nitrogen in weeks 2–4, then shifts to phosphorus and potassium from week 5 onward. Calcium and magnesium supplementation is frequently required under LED fixtures; 100–150 ppm Ca and 40–60 ppm Mg are common baselines. Silica at 50–100 ppm can improve stem rigidity and stress tolerance without compromising resin.
Training should remain gentle due to the fixed life clock of autos. Low-stress training beginning around day 18–24 helps open the canopy, and light defoliation of large fan leaves around day 28–35 improves airflow. Avoid topping after day 21; if topping is used at all, it must be precise and early to prevent slowdown.
Indoor yields for well-tuned autos often range from 350–550 g/m², with experienced cultivators sometimes reaching 600+ g/m² in high-density layouts. Outdoor, expect 40–120 g per plant depending on sun exposure, pot size, and season length. CO2 enrichment to 800–1,000 ppm can add 10–20% biomass in controlled environments if light and nutrition are sufficient.
Integrated pest management should begin at seedling with weekly visual inspections and sticky cards. Neem or karanja oil at 0.5–1% as a preventative in veg, combined with Bacillus thuringiensis israelensis for fungus gnat control, creates a solid baseline. Maintain intake filters and oscillating fans to deter powdery mildew; aim for 0.5–0.7 air exchanges per minute in tents.
As flowers stack, support branches with soft ties or netting to prevent lodging. Keep canopy density moderate; remove interior larf around day 40–45 to redirect energy to tops. Late-flower leaf stripping should be conservative to protect photosynthetic capacity in the final push.
Harvest timing is best judged by trichomes under 60–100x magnification. For a balanced hybrid effect, target roughly 5–15% amber trichomes with the majority cloudy; for a heavier finish, let amber approach 20–25%. Pistils alone are not reliable; use them only as a secondary cue alongside trichome maturity.
Pre-harvest practices can include reducing EC to 0.4–0.6 mS/cm for the last 5–7 days to encourage clean burn. Some growers drop night temperatures by 2–4°C in the final week to preserve terpenes and coax color. Dark periods longer than 24 hours pre-chop are anecdotal; if used, ensure adequate airflow to prevent condensation.
Drying should occur at 18–20°C and 55–60% relative humidity for 10–14 days until small stems snap cleanly. Post-dry, cure in glass at 58–62% RH, burping daily for the first week, then weekly for 3–4 weeks. Water activity between 0.55–0.62 stabilizes aroma and slows terpene volatilization.
For odor control, a properly sized carbon filter matched to fan CFM is essential; calculate at least one full air exchange per minute for tents. Keep exhaust ducting short and with minimal bends to maintain static pressure. If smell is a priority, avoid handling buds in living spaces and schedule trim sessions in ventilated areas.
Common issues include calcium deficiency under LEDs, presenting as interveinal rusting on new growth around weeks 4–6. Address early with a balanced Cal-Mag dose and confirm pH is in range. Overwatering seedlings is another frequent pitfall; allow the top 2–3 cm of medium to dry before rewatering in the first two weeks.
If pursuing extracts, note that total terpene content of 1.5–2.0% and THC in the high teens to low 20s can produce flavorful rosin at 18–22% yield from well-cured flowers. For solventless pressing, keep humidity in the 60–62% jar range for pliable, stable resin. Excessively dry material can reduce yields and mute citrus notes.
Staggering plantings every 3–4 weeks enables continuous harvests due to the auto schedule. Pairing Auto Original 47 with other autos of similar finish times keeps canopy management predictable. Given its size and timeline, it fits well as a perimeter crop around slower photoperiods without light schedule conflicts.
